The whole procedure of open appendectomy involves the patient going to the supine position, local anesthesia and sterilization, finding the surgical site to make an incision, opening the abdominal cavity to find the appendix to be removed, and suturing and bandaging the appendix. The procedure usually starts with the patient lying in the supine position, and then the right lower abdominal McClintock incision is found for disinfection and anesthesia. The area is usually sterilized with iodophor and the periphery of the surgical area is 15 cm or more. The choice of anesthesia is usually lumbar (semi-anesthesia). After successful anesthesia, an incision is made at the point of the mackerel, gradually separating and opening the abdominal cavity to locate the appendix. After removal of the appendix, the stump is closed with purse-string sutures, and finally the appendix stump is encased in the cecum and covered with peritoneum. The peritoneum is covered and then sutured layer by layer to close the abdominal cavity, and finally the skin is sutured, sterilized and bandaged, and the operation is completed. Postoperative antibiotics such as ceftriaxone sodium and levofloxacin are routinely administered intravenously to ensure that the inflammation subsides. Postoperative diet, need to wait for the recovery of gastrointestinal function.
